In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects.
PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.

In the practical application of high-speed CNC engraving and milling machine, most of the faults are caused by the damage of the machine components. How to deal with them in time will directly affect the normal use. In severe cases, the entire machining accuracy will also be affected. Next Xiaobian will simply introduce you as a user, how we should maintain high-speed CNC milling machine parts.
1, in the operation of high-speed CNC engraving and milling machine, we must ensure that the guide surface is clean, do not have chips, abrasive particles, etc. fall on the top, if any, will increase the friction of the guide, but also lead to rust and so on.
2. Maintenance and maintenance of the guide rails need to be performed on a regular basis, and the amount of guide rail lubricants should be checked daily. If the oil is not enough, lubricants should be added.
3. Regularly check whether the oil pump can be started and stopped regularly, and pay attention to whether the oil can be provided at startup.
4. Guide rails need to be kept lubricated to avoid problems such as friction, resulting in increased temperatures. The guide rails are normally lubricated automatically. If it is found that the guide rails are not lubricated, check the diverter valves.
5, when processing graphite and ceramics, please use graphite high speed engraving and milling machine. Because the processing of graphite and ceramic materials, processing dust, easy access to the guide, affect the service life.
6. During the operation of the high-speed CNC engraving and milling machine, the user should always pay attention to its running status and do regular maintenance work, so as to maintain the high-speed engraving and milling machine operation effect, extend its life and ensure the quality of engraving and milling. .
How to maintain high-speed CNC engraving and milling machine parts?
In the past few years, the domestic machine tool industry, especially in the field of metal cutting machine tools with high technological content, has experienced a continuous increase in machine tool output. For example, high-speed CNC engraving and milling machines have been used for many years. The demand has increased year by year. Compared to ordinary engraving machines, high-speed CNC engraving and milling machines have increased the power of spindles and servo motors, the bed bearing capacity, while maintaining the high-speed spindle, and more importantly, the precision is high. In addition, the high-speed CNC engraving and milling machine has a stronger cutting ability and a very high processing accuracy. It can also directly process materials with hardness higher than HRC60 and can be molded once.
